If you are taking a blood pressure and the first pulse you here is at the number 123 and the last pulse you hear is at 85, how would you correctly report that person's blood pressure? (Don't
forget units)

i think the answer is a, hope this is right, that would be my best guess.

c. magnitude and direction

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
